APPARATUS FOR MAKING CYLINDER-GLASS.

SPECIFICATION forming part of Letters Patent No. 792,590, dated June 20,1905.

' Application filed November 16, 1903. Serial No. 181,333.

To all 11 710711 it may concern:

Be it known that I, JONATHAN HALnY, a citizen of the United States ofAmerica, residing at Akron, in the county of Summit and State of Ohio,have invented certain newand useful Tmprovements in Apparatus for MakingCylinder-(jrlass; and I hereby declare the following to be a full,clear, and exact description of the invention, such as will enableothers skilled in the art to which it pertains to make and use the same.

This invention relates to improvements in apparatus for makingcylinder-glass to be used for window-glass.

The primary object of this invention is to provide apparatus which issimple in construction and convenient and reliable in its operation andwhereby cylinder-glass can be made or formed with great facility.

Another object of this invention is to draw a limited mass ofglass-metal into the form of a cylinder which is uniform in thicknessand diameter from end to end.

\Vith these objects in view and to the end of realizing other advantageshereinafter appearing this invention consists in certain features ofconstruction and combinations of parts hereinafter described, andpointed out in the claims.

in the accompanying drawings, Figure 1 is an elevation, largely insection, of apparatus embodying my invention, and portions are .brokenaway in this figure to reduce the size of the drawing. Fig. 2 is a topplan in section on line 2 2, Fig. 1, illustrating a portion of theapparatus. Fig. 3 is a top plan, largely in section, on line 3 3, Fig.1, and portions are broken away in this figure to reduce the size of thedrawing and to more clearly show the construction. Fig. A is anelevation of a portion of the glass-metal-su ppl y chambcr,largel y invertical section, on line 4: 4t, Fig. 3, looking in the directionindicated by the arrow. Fig. 5 is an elevation, largely in section andcorresponding with Fig. 4:, except that in Fig. 5 the floating vessel isshown hoisted or elevated into its upper position and the glass-coolingmeans and the glass-drawing means are shown in position for operation.Fig. 6 is an elevation, largely in section and corresponding with Fig.5, except that in Fig. 6 the glass is shown drawn from the floatingvessel through the respective glass-drawing aperture of theglassmetal-supply chamber. in section on line 7 7, Fig. 6.

Referring to the drawings, A designates a tank having an interiorchamber (0, containing a body of molten glass or glass-metal G. The saidbody of glass-metal is kept in a suitably molten condition in anyapproved manner. Means for producing a body of molten glass orglass-metal and maintaining it in a suitably molten condition are toowell known to require description or illustration in this application.

The chamber a is the glass-metal-supply chamber of my improvedapparatus. Within the said chamber are arranged two floating vessels D.The top wall B of the vessel-containing portion of the said chamber isoffset downwardly, as at 10, so as to bring the lower portion 12 of thetop wall of the said portion of the said chamber as closely aspracticable to the body of glass-metal within the said chamber.

Each vessel D is arranged within the chamber at, below a circularopening or glass-drawing aperture Z) formed in and extending verticallythrough the lower portion 12 of the wall B, which is provided with a lidor cover a for closing the said aperture. Each vessel D is provided witha centrally-located upwardly-projecting stem (Z. Each vessel D has anannular chamber 13 formed at and extending around the lower end of thestem (Z of the said vessel, and the opposing side walls of the saidchamber slope toward each other in the direction of the bottom of thesaid chamber. The said chamber 13 is open at the top of the vessel allround.

A vessel D to [ill the chamber 13 thereof with glass-metal is depressedor lowered into the body of glass-metal Cr within the chamber a. In Fig.4: avessel D is shown lowered into the said body of glass-metal G andfilled with glass-metal g, which has flown into the vessel from the saidbody of glass-metal. The stem (Z of a vessel D in the upper position ofthe Fig. 7 is a top plan vessel extends centrally and verticallythroughthe respective aperture 0, as shown in Figs. 1, 5, and 6, such adistance that the cover 0 for the said aperture during the closing ofthe cover comes into engagement with the upper end of the said stem andthereupon lowers the vessel into the body of glass-metal G to the extentrequired to result in the flow of glassmetal from the said. body intothe chamber 13 of the said vessel. The desired level of molten glass orglass-metal is of course maintained within the chamber 11'.

Apparatus for drawing glass-metal from within a vessel D upwardly andvertically into the form of a cylinder is upon opening the cover a,which closes the aperture 7) over the said vessel when the latter hasbeen filled with glass-metal, brought into operation and comprises,preferably, a truck T, arranged (see Figs. 1 and 3) adjacent to andmovable alongside of the vessel-containing portion of the chamber a,which truck has a platform P arranged in the same plane horizontallywith the top wall of the vessel-containing portion of the said chamber.A standard-forming cylindrical column F, which is arranged verticallyupon and secured in any approved manner to the platform P, is suitablybraced from the platform. The upper end of the column F forms thepivotal bearing of a frame H, which is capableof being swung laterallyand provided with a vertically-arranged journal 15, embracing the saidend of the said column and seated or resting on a seat-forming collar 1,with which the column is externally provided. The frameH is thereforepivotally mounted to render it capable of being swung laterally in ahorizontal plane, and means for locking the said frame against swinginglat erally preparatory to the drawing of glassmetal from a vessel 1) isprovided and comprises, preferably, a latch K, which in its 0perativeposition engages a slot or recess J formed in the collar 1. The latch1((sce Fig. 1) is pivoted horizontally, as at 1, a suitable distanceabove the lower end and at one side of the journal 15 to a bracket 16,with which the said journal is externally provided, and any suitablemeans such, for instance, as a poise or weight m-is applied as requiredto retain the latch K in its operative position. The latch K is shown inits operative position in Fig. 1 and obviously is rendered inoperativeby swinging it out of engagement with the slot J against the action ofthe weight 7 and the frame H is rendered free to be laterally swungcircumferentially of the column F by rendering the said latchinoperative.

The frame H extends laterally of and a suitable distance above thecolumn F. The frame H is provided at one side and a suit able distancefrom the journal 15 with a vertically-arrai'iged cylindrical guide 17,which loosely embraces and affords lateral bearing to thecorrespondingly-arranged cylindrical and tubular shank or stem L of achuck or holder L, arranged below the said guide and employed insupporting the ring or annular tool R, employed in drawing glass-metalfrom within a vessel D iu nvardly into the form of a cylinder 0, asshown in Fig. 1. The stem L is rigid with the inverteddish-shaped bodyportion 18 of the holder L. The body portion 18 (see Figs. 1 and 3) isprovided at its lower end with two oppositely-arranged cooperatingjawsZO,embracingoppositesides,respectively, of the ring R at the upperend of the ring. The jaws 20 are adjustable toward and from each other.The body portion 18 of the holder L is provided with two parallelslideway-forming bolts M, arranged horizontally at oppositesides,respectively,of the said body portion and arranged parallel withthe line of adjustment of the said jaws. Each bolt M extends through acorrespondingly-arranged car 22, formed upon the body portion 18, andthrough two correspondingly-arranged cars 23, formed upon the differentjaws, respectively, at opposite sides, respectively, of the said ear.The bolts M are arranged with their heads at the outer sides of the cars23 of one of the jaws 20, and nuts an. are mounted on the shanks of thebolts at the outer sides of the other of the said jaws. The bolts 11 andnuts m cooperate in securing the jaws 20 in the desired adjustment, andthe ring R is tightly clamped by and between the said jaws or renderedfree to be removed according as the nuts are tightened or loosened.

The holder L is suspended from a cable which is attached at one end tothe body portion 18 of the said holder in any approved manner. The cableZleads upwardly from the holder L exteriorly of and along the stem L toand over a vertically-arranged guide-sheave K, supported from theframework H adjacent to the guide 1'7, thence leads laterally to andover another vertically-arrangcd guidesheave Z supported from the frameH adjacent the upper end of the journal 15, and thence leads downwardlyinto and through the column F to and in under and operativcly engages awindingalrum i which is operatively mounted on a horizontallyarrangedshaft 25, supported from the truck T. A spur-gear 26 is loosely mountedon the shaft 25, and a clutch :27 is provided for establishing andinterrupting operative connection between the said gear and the saidshaft. The gear 26 meshes with a pinion 28, operatively mounted on ashaft 30, which is arranged horizontally and parallelly with the shaft25 and supported from the truck T. The shaft 30 is operatively providedwith a spur-gear 32, which meshes with a pinion 33, operatively mountedon the shaft 34: of an engine or motor Q on the truck T. It will beobserved, therefore, that operative connection between the drum Z andthe engine or motor is controlled by the clutch 27. Power is transmittedto the drum-bearing shaft 25 from the engine or motor Q, to hoist theholder Q, and the connected glass-drawing ring or tool R.

The drum-bearing shaft 25 is operatively provided with a ratchet-wheel35, and a pawl 36, which is pivotally supported from the framework ofthe truck T, engages the said wheel. The ratchet-wheel 35 and pawl 36are arranged as required to prevent the rotation of the drum Z in thedirection required to pay out the cable engaging the drum. The drum Z isrendered free to pay out the said cable upon disengaging the pawl 36from the wheel 35.

By the construction hereinbefore described it is obvious that the holderL and the glassdrawing ring or tool R, carried thereby, lower by gravityand are hoisted by power transmitted from the engine or motor. I wouldhere remark that the ring R is of metal and that glass-metal willreadily adhere to the lower end of the said ring when the latter at thesaid end becomes suitably heated, which it does upon being lowered intocontact with the glass-metal to be drawn from a vessel D.

A pipe 1/, which is shiftable endwise, is arranged vertically andcentrally of the stem L of the holder L. The pipe a extends a suitabledistance below the stem L, and a hose or flexible tube :1: is attachedin any approved manner at one end to the upper end of and communicateswith the pipe u and at the opposite end communicates with the outlet ofa rotary fan or blower 38, which is operatively connected in anyapproved manner with the engine or motor Q. The pipe 10 is providedwithin the stem L with a slide-forming collar a. It will be observed,therefore, that the stem L forms a vertically-arranged slideway for theslide a and that the pipe it depends from the said slide and at theslide communicates with and is attached to the flexible tube w. The tube:11 leads over a guide-sheave '0', supported from the upper end of thestem L.

The blower or fan 38 is mounted on the truck T and communicates at itsinlet with the external atmosphere. Obviously the operation of the fanor blower 38 results in the passage of air through the connected hose ortube 11 into the pipe 24 and thence into and through theinverted-cupshaped nozzle 2 with which the said pipe at its lower end isprovided. The nozzle ;1 has the shape and dimensions required to renderit capable in its lower portion of embracing the upper portion of thestem (Z of a vessel 1). The nozzle 3 is provided with laterallyoutwardly discharging orifices 40, some of which are 10- ct ted at andat short intervals circumferentially of the lower and transverselylarger end of the nozzle, which is cylindrical at the said end. Thenozzle y (see Figs. 1, 2, and 5) is &

upon the lower end whereof are formed two laterally-projecting members42, arranged at opposite sides, respectively, of the stem. The said stem1/ is adapted to engage a hole d, formed in and centrally of the upperend of the stem (Z of a vessel D, which hole is just large enough at itsupper end to accommodate the reception thereby of the said stem and itsprojecting members 42, but is undercut at its lower end and at oppositesides, as at 43, to accommodate the turning of the said stem half-wayround when the said stem is lowered into the said hole. In dotted lines,Fig. 7, the stem y is shown in position to enter the aforesaid hole (1',and obviously the turning of the nozzle 7 half-way round when its stem 9has been lowered into the said hole (1 will bring the projecting members42 of the said stem into the lateral enlargements of the lower end ofthe said hole, and thereby attach the vessel to the nozzle, as shown inFig. 5.

A cable If, employed in hoisting and lowering the pipe at and attachmentor attachments, is provided and operatively attached at one end in anyapproved manner to the said pipe at the upper end of the pipe adjacentthe discharging end of the tube The cable u leads from the pipe aupwardly to and over a vertically-arranged guide-sheave 20 supportedfrom the frame H at the upper end of the said frame, thence downwardlyinto engagement with a vertically-arranged guide-sheave ll supportedfrom the said frame above and near the sheave Z and thence downwardlyinto the column F, and thence laterally through a lateral aperture f,with which the said column is provided, into engagement with a windingdrum or wheel a, which is supported from a bracket 44, with which thesaid column is provided externally at one side of the said aperture. Aratchet-wheel 45 is operatively connected with the drum or wheel a" andarranged with its axis coincident with the axis of the said drum orwheel a. A pawl 46, which is pivotally supported from the bracket 44,engages the ratchet wheel 45. The ratchetwheel 45 and pawl 46 arearranged to prevent rotation of the drum or wheel a in the directionrequired to pay out the cable a. The drum or wheel a is free to turn inthe direction required to wind up the engaging cable and is renderedfree to pay out the said cable upon disengaging the pawl 46 from theratchetwheel 45. Obviously the pipe at and attachment or attachmentslower by gravity when the drum or wheel a is paying out the cable a andare hoisted by winding up the said cable.

It will be observed that by the construction and arrangement of partshereinbefore described the glass-drawin ring or tool It and the nozzle 3are readily brought into the proper position relative to theglass-drawing aperture 7), through which glass-metal is to be providedcentrally with a depending stem y, 1 drawn. It is obvious, of course,that the frame II is so adjusted relative to the said. aperture as tobring the glass-drawing tool R directly into line vertically with thesaid aperture, and obviously when the said tool is arrai'iged asrequired relative to the said aperture the pipe 1/. and attached nozzle,which pipe has lateral bearing in the body portion 18 of the holder L.as at 4:7, Fig. 1, will be arranged as required relative to the saidaperture. The vessel I), located in under the said aperture, has suchdimensions and arrangement relative to the said aperture and relative tothe diameter of the glass-drawing ring R that the chamber 13 of the saidvessel, although arranged in the main in under the said aperture, hasits outer portion extending in under the portion 12 of the wall B, andglass is drawn from the said chamber all round the stem (Z of the saidvessel centrally between the side Walls of the said chamber.

Each vessel D is guided vertically by stationary vertically-arrangedposts 48, provided within the chamber a at suitable intervals around andin close proximity to the vessel.

In Fig. 3 one of theglass-drawing apertures is shown closed and theother open. In Fig. 5 the glass-drawing ring R is shown lowered into anopen aperture and into contact with the mass of glass-metal within thevessel 1) in under the said aperture, and the pipe at and attachednozzle y are shown lowered, and the said vessel is shown attached to thesaid nozzle and elevated far enough to interrupt communication betweenthe body of glass-metal G exteriorly of the said vessel and theglassmetal r in the said vessel. In Fig. 1 cylinderglass 0 is shownbeing drawn from a vessel I), and in Fig. 6 the said vessel is shownempty and detached from the nozzle 1 and the cylinder-Mass drawn fromthe vessel and the pipe 11 and attached nozzle 1/ are elevated farenough to accommodate the removal of the cylimler-glass C from the stem(1 of the said vessel.

In the operation of my improved apparatus glass-metal is drawn throughthe different apertures alternately, and the cover which closes theaperture through which glass is next to be drawn and which in its closedposition holds the vessel II) arranged in under the said aperture in itsimmersed or lower position, is opened, whereupon the pipe w,- is loweredto bringthe depending stem 1/ of the nozzle into line with the hole d,formed in the stem (l of the said vessel. The said nozzle is then givena half-turn to effect the attachment of the respective vessel 1.) to thenozzle-stem 7 whereupon the pipe a is hoisted to lift the filled vesselabove the level of the body of glass-metal (Jr within the chamber asshown in Fig. The glass-drawing ring It is then lowered, if not alreadylowered, but may be lowered simultaneously with the lowering of the pipe1/. far enough to bring the said ring into engagement with theglass-metal in the lifted vessel I), whereupon the said ring is hoistedgradually to form cylinder-glass, as shown in Figs. 1 and 6, and whilecylinder-glass is being drawn the fan or blower 38 is operated to supplyair to the nozzle y for use in cooling the said glass, but not underpressure sufiicient to injure the glass.

I would here remark that the drawing of glass-metal from an annularchamber 13 of a vessel 1) centrally between the dmmwardlyconverging sidewalls of the said chamber is invaluable in the formation with facilityof cylinder-glass which is uniform in thickness and diameter from end toend of the cylinder. The provision of the inverted-cup-shaped nozzle yat the lower end of the pipeaand adapted to embrace the upper end of thestem (Z of a vessel 1) is also of great importance. The said nozzle atits lower end is not quite as large transversely as the cylinder ofglass to be drawn, so as not to come in contact with the said cylinder.Some of the orifices of the nozzle are located so that air is dischargedin close proximity to the surrounding wall of the interior chamber ofthe cylinder and at or .in close proximity to the upper end of theapertu re 6, through which the glass is being drawn, so that the glassdrawn in the formation of the said cylinder is immediately orapproximately immediately cooled and solidilied upon drawing it throughthe said. aperture. The suspension of the ring-holder L and the pipe afrom a frame which is capable of being swung laterally is also notunimportant, because thereby the said pipe and the glassdrawing ring Rcan be simultaneously swung to and over or from over a glass-drawingaperture 7). Also the holder L, being invertedcup shaped, accommodatesthe hoisting of the nozzle 7 into and above the lower end of the ring Rto facilitate the removal of a cylinder of glass drawn by the said ring.In Fig. 6 the nozzle y is shown hoisted above the lower end. of the ringR, and obviously the cylinderglass shown in the said ligure and elevatedfar enough to free the stem (Z of the respective vessel 1) can be swunglaterally to accommodate the closing of the cover for the aperture 6,through which the said cylinder has been drawn, whereupon the cover overthe other aperture 6 is opened for the purpose of drawing glasstherethro ugh. As already indicated, the rendering of the latch Kinopera tive accommodates the lateral swinging of the frame II whennecessary, and the mounting of the said frame upon a truck facilitatesthe movement of the glass-drawing apparatus and pipe-shi fting apparatusalongside of the glassmetal-supply chamber (1'.
